Constructor Detail

EntityCapabilities

public EntityCapabilities(String node,
                          String hash,
                          String ver)

Parameters:

node - The node.

hash - The hashing algorithm used to generate the verification string, e.g. "sha-1".

ver - The verification string.

Method Detail

getVerificationString

public static String getVerificationString(InfoNode infoNode,
                                           MessageDigest messageDigest)

Gets the verification string as specified in XEP-0115, 5. Verification String.

Parameters:

infoNode - The root node of the service discovery. It has information about the entities features and identities as well as extended service discovery information.

messageDigest - The hashing algorithm. Usually this is SHA-1.

Returns:

The generated verification string.

getHashingAlgorithm

public String getHashingAlgorithm()

Gets the hashing algorithm used to generate the verification string.

Returns:

The verification string.

See Also:

setHashingAlgorithm(String)

setHashingAlgorithm

public void setHashingAlgorithm(String hash)

Sets the hashing algorithm used to generate the verification string.

Parameters:

hash - The verification string.

See Also:

getHashingAlgorithm()

getNode

public String getNode()

Gets the node.

A URI that uniquely identifies a software application, typically a URL at the website of the project or company that produces the software.

It is RECOMMENDED for the value of the 'node' attribute to be an HTTP URL at which a user could find further information about the software product, such as "http://psi-im.org" for the Psi client; this enables a processing application to also determine a unique string for the generating application, which it could maintain in a list of known software implementations (e.g., associating the name received via the disco#info reply with the URL found in the caps data).

Returns:

The node.

See Also:

setNode(String)

setNode

public void setNode(String node)

Sets the node.

Parameters:

node - The node.

See Also:

getNode()

getVerificationString

public String getVerificationString()

Gets the verification string that is used to verify the identity and supported features of the entity.

Returns:

The verification string.

See Also:

setVerificationString(String)

setVerificationString

public void setVerificationString(String verificationString)

Sets the verification string.

Parameters:

verificationString - The verification string.

getVerificationString()

getPriority

public int getPriority()

Specified by:

getPriority in class StreamFeature

toString

public String toString()

Overrides:

toString in class Object
